Hi Dave

Looking on line, Cornus kousa 'John Slocock', popped out, but what I know of Cornus you could write on the head of a pin, and still have room for a hornpipe. Hence my seeking out any Cornus gurus.

Here in Cornwall, the winter temps are quite mild, and some decidous plants stay evergreen.

Thanks for the I/P

Seems a bit late for Cornus kousa flowering.....also a bit large. I'd guess Cornus capitata based on leaf shape and flowers and overall habit.

Thanks. I should also have mentioned that this was taken .. wow. Beginning of June? What have I been up to? :-)))))))

Is that better for C.kousa flowering?

Yes, that makes much more sense :-) But leaves still look a bit too large and the form/habit off for the kousas I am used to. They most often tend to be much wider than tall.

It's one of the evergreen dogwoods related to Kousa dogwood. There are also named crosses between them to consider.

That was what was made me wonder. It doesn't seem to match the online descriptions, very well, but all plants do their own thing. They never bother going online, so don't realise what they "should" look like.

Thank you. I guess C. kousa cv will have to do.

It's not a kousa, it's one of the related evergreen species or - probably less likely - one of their garden hybrids.

Species delimitation within this subgenus is controversial. Over 15 new taxa have been published since the 1950s. This treatment follows Xiang (Bull. Bot. Res., Harbin 7(2): 33–52. 1987), who recognized 13 subspecies among four species, i.e., Cornus capitata, C. hongkongensis, C. kousa, and C. multinervosa. However, a preliminary allozyme investigation by Dudley and Santamour (Phytologia 77: 425–430. 1995) suggested that C. capitata subsp. capitata is quite divergent from C. capitata subsp. angustata. Thus, in the present treatment, we recognize C. elliptica as a species separate from C. capitata. Further studies are needed to test the various species delimitations in the group.

Thanks Embothium

Going to be sitting on a trains, tomorrow, for about 8hrs. Plenty of time to have a good look at the link. Looks interesting.

Cornus elliptica was originally designated as C. kousa var. angustata. It has also been called Cornus capitata var. angustata and Cornus angustata. In any case, very confusing names for evergreen dogwoods.

Here in the Eastern US, this blooms around the first part of July. But there may be a few flowers later on.

Tree asked about needs to be studied in person, with a view to particular details used at this time to differentiate the involved species (see dichotomous key at above link to Flora of China) before a determination can be made.
